Blender 2.83 runs VERY SLOW: constantly accesses HDD even though it's installed on SSD
This is how I fixed the problem, though Blender does still run fairly slow on this particular file since it is very large. However, I had corrupted Windows files. I didn't know that until my Task Manager started acting oddly.
This is what I did to fix:
Using the CMD application in Windows 10, as an administrator, I ran the following command: &quot;sfc /scannow&quot;. That scan indicated I had some corrupted files.
Them, from CMD as an administrator, I ran &quot;DISM.exe /Online /Cleanup-image /Scanhealth&quot;. This let me know the faults were repairable.
3). Then, from CMD as an administrator, I ran &quot;DISM.exe /Online /Cleanup-image /Restorehealth&quot;. This fixed the faults.
After the above steps, my D: drive has not been being accessed at all by Windows. It's right at 0% all the time now. Earlier, the norm was 90% or higher.
